Thai authorities should drop all charges pending against journalist Nutthaphol Meksobhon and photographer Natthapon Phanphongsanon and stop harassing the press for reporting on issues related to the nation’s monarchy, the Committee to Protect Journalists said on Wednesday.

Nutthaphol, a reporter with the local independent Prachatai news website, and Natthapon, a freelance photographer, were arrested and charged on Monday by the Royal Palace Police Station with collaborating in vandalizing a sacred historical site, according to multiple press reports.

The charges stem from their reporting in March 2023 that an activist spray-painted graffiti on the outside wall of the Temple of the Emerald Buddha in the capital Bangkok’s Grand Palace complex, those sources said.

The journalists were released on 35,000 baht (US$980) bail on Tuesday after being detained overnight. Charges under the Cleanliness Act and Ancient Monuments Act combined carry a maximum seven-year prison sentence and 700,000 baht fine (US$19,600), those sources said.

Several reporters were at the scene of the incident, according to reports, and it is unclear why Nutthaphol and Natthapon were singled out.

“Nutthaphol Meksobhon and Natthapon Phanphongsanon should not be threatened with lengthy jail sentences for merely doing their jobs as journalists in reporting on a social activist’s vandalism,” said Shawn Crispin, CPJ’s senior Southeast Asia representative. “If Thailand wants to be taken seriously as a democracy, it should start acting like one by allowing the press to do its job without harassment or fear of arbitrary reprisal.”

The activist spray-painted an anarchist symbol and a crossed-out number 112 on the wall, in reference to Article 112 in Thailand’s Criminal Code, which provides for up to 15-year prison sentences for anyone found guilty of insulting the king, queen, heir apparent, and regent. Mass protests in 2020 and 2021 and the opposition Move Forward Party have called for reforms to the so-called lèse majesté law.

Prachatai is known for its consistent reporting on royal affairs, including on activists and others who are charged and jailed under Article 112.

Prachatai editor-in-chief Tewarit Maneechai was quoted by news agencies as saying that the arrests were “an act of intimidation” that “created fear about news coverage of sensitive issues.” He said the reporters were unaware of the charges against them prior to their arrests.

Thailand’s Royal Police Headquarters did not immediately reply to CPJ’s emailed request for comment on the charges.
